Analogue Delay

[SillyOctpuss]

I have 3 MN3005s and nothing to put them in. I was saving two of them for the Madbean tap tempo delay but I don't think we'll see that now.

Is there an analogue delay on the site or plans for one in future?

I second this. I’m not a huge fan of how the FV1 sounds and I love me analog delays (I own at least 4 of them) and I can never have enough. Having some advanced features like eq control, fx loop, input gain control, expression controls would really seal the deal. Should I just buy a Moogerfooger?!?

I don't know if this is a forum faux pas but the best analog delay I've heard, and definitely the best as a diy PCB is the Lectric FX DC Echo. It takes 3 MN3005s and you can power it with a standard 9 volt supply. It's like a Deluxe Memory Man but better. WAY better. They are out of stock at the moment but keep checking back:

Schematic now available; see below. Hmm, a cleaner and brighter version of a Deluxe Memory Man™? A faithful reproduction of the Electro-Harmonix™ Echo 600, an EXTREMELY rare pedal from the very early eighties. Read more in the following document! Note: If using a 3pdt pcb from us (or any other...

Wow that's a monster. I want one

Nah, no one will kick you out here. Even if you write things like me: "there are way too many OD pedals here".

See? Still not kicked out. (I think...)

14 ICs, 8 trimpots! This is insane.

How long is the delay on this thing?

600 ms. If you can tolerate the quirks of a BBD delay, this one is the best. Not for me, but as good as they get.

 

[giovanni]

But what about the fx loop? And the expression control?

 

[JamieJ]

"there are way too many OD pedals here".

Is there such a thing?

 

[Feral Feline]

Definitely will pick up the DC-Echo at some point.

I talked to Lectric FX today and he told me that in 7-10 days they should have more DC Echo PCBs in stock. They've been ordered, he's just waiting for them to come in.

I looked up the MN3005 chip and they sell them on Small Bear for $21!!!
Any cheaper source?

maybe the Coolaudio or XVive remake version?

EDIT: Nevermind, the Small Bear version is the XVive repro version. Man, they are pricey.

He must be getting a bunch of emails from this board, I feel bad for bombarding him now, I emailed him the same question yesterday after reading it here. Guess I better keep checking so I don't miss them this time.

Just thought I'd share how I set up my DC Echo in case its helpful to anyone else. I was going a little buggy going back and forth with the gain trimmers as described in the build docs trying to balance things out when I made a discovery. Gain1 and Gain2 determine when and if the feedback knob sends to circuit into runaway oscillations. Instead of using an audio probe and test points, I plugged in a guitar,
I set it to short mode, and turned the delay and feedback knobs all the way up. I adjusted Gain1 until it just started to runaway. Then switched it to long mode and did the same with Gain2. This gave me a perfect level balance across both modes and blend extremes. And it goes into runaway feedback in both modes only when the knob is all the way up.

I wouldn't feel bad. At least he knows a load of people want to buy his pcb. That's bound to be better than stocking something no one wants or buys.

I bought mine in 2017/18 and they were pretty expensive even back then to be honest. They are very good though.

 

[SillyOctpuss]

I usually get them from cabintech but they are out as well. Analog delays are expensive for a reason. Between 5 I have built there are 10 mn3005s lol

They're 100% worth it though.

I totally was not expecting the price tag. Are these the chips used in a Carbon Copy or a modern DMM?

No the carbon copy uses mn3208 chips which are or at least were a lot cheaper last time I looked. No idea on the modern DMM

Edit - just had a look and banzai have the 3208s in stock at €3.95
